“I’m running for the U.S. House to serve and work for the people of Montana. I pledge to always listen, represent our values, and protect our Montana way of life. With all the gridlock and fighting back in the swamp, it’s clear Washington D.C. could learn a thing or two from Montana,” he said in a statement.

“I’ve rolled up my sleeves to get to work to deliver affordable and better health care to Montanans, took on the pharmaceutical industry to lower drugs costs, protected and expanded access to our public lands, and brought fiscal discipline to my office – and I’ll do the same as your next Congressman.”

In a campaign video released Monday, Rosendale also touted his work on the state’s health care policy. Democrats used health care as a key campaign issue and were able to take over the House last year.

Rosendale has already garnered the support of conservative political action group Club for Growth, which tweeted its endorsement of the candidate shortly after his announcement.

“@club4growth PAC is proud to endorse Matt Rosendale for Congress!," the group said in a tweet. "@MattForMontana is precisely the type of leader needed in Washington. He has the guts to take on the establishment & and will fight to advance @realDonaldTrump’s pro-growth economic agenda."
